To all whom it may concern.'

Be it known that I, WILLIAM HAXTON, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Perambulator- Sleds; and l do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. s,

This invention relates to a permabulator sled and has for its obj ect the construction of a sled or sleigh adapted to be quickly converted into and used as a Wheeled perambulator for infants.

The invention also has for its object the construction of a strong, cheap, simple and durable interchangeable vehicle of which the wheels can be quickly swung up out of supporting position when it is -desired to use the vehicle as a sled.

It is also a further object of the invention to provide a ruiming gear for a wheeled vehicle which may be quickly attached and adjusted to a sleigh of any preferred or usual construction thereby obviating the necessity for procuring a sleigh of special make.

The invention also embraces simple and positively operated mechanism for adjusting the parts relatively of each other and consists in the matters hereinafter described and more fully pointed out and defined in the appended claims.

ln the drawings: Figure l is a side elevation partly in section of a device embodying my invention showing the same adjusted as a wheeled perambulator. Fig. 2 is a rear elevation of the same. Fig. 3 is a fragmentary Fig. 4 is a detail of the lock for the adjusting rod. Figs. 5 and 6 are side elevations of the connecting knuckles.

As shown in said drawings: A, A/ and A2 indicate the knees of the sled which may be constructed inany suitable manner and support the body a upon the runners a/ as is usual. `Said knees as shown are three in number though of course any desired number may be used. Rigidly secured upon the front and rear knees are brackets BMB/ which are bolted on the inner side of each of said knees and are shaped to afford a pivot bearing for the yoke arms b on which the wheels C-C are journaled. Said arms may be of any desired length to suit the height at which said brackets are secured above the runners and carry the bearings or journals foi` the wheels thereon at or near said runners so that the wheels when thrown downwardly project below the runners.

Each bracket as shown is provided at the rear side with a downwardly directed integral wall or shoulder b2 which permits the wheel carrying arm to assume a prevents the same from swinging backwardly. Said brackets are open on the front side however so that said wheels may be swung forwardly and upwardly as shown in dotted lines in Fig. l permitting the sled to be sup ported upon its runners. Connecting the wheels on each side at the axles is a rigid bar D provided with a turnbuckle d therein whereby its length can be ad justed to approximately the distance between the brackets. Said bar D is provided at its ends with split knuckles d which have threaded engagement thereon and are engaged on the axle shafts d2.

lnasmuch as the knees of different makes of sleds are not arranged at the same angle to the perpendicular it is necessary to provide means for adjusting the yoke arms b to the perpendicular and for this purpose as shown a set screw b3 is provided in each shoulder b2, the inner end of which impinges the yoke arm below its pivotal point and may be set to limit the rearward swing thereof,

llournaled transversely of the rear knee in suitable brackets is a shaft E secured to which are forwardly directed levers c one on each end thereof and which are provided on their lower ends with knuckles c having threaded engagement thereon and to which are pivotally engaged by means of knuckles e2 similar to the knuckles d, the outer ends of the connecting rods e3 the Opposite ends of which are secured by knuckles similar to the knuckles ef to the pivot or axle of each rear wheel. Secured as shown near the middle of said shaft E is a rearwardly directed arm e4, shaped on its under side at its outer end to be engaged by the foot and near the outer end thereof is pivotally secured an adjusting rod c5 which extends upwardly at the rear end ofthe sled and through a suitable bracket e6 provided with an inwardly directed detent or tongue e7 adapted to engage in notches eS in said adjusting rod and hold the same in adjusted position. Secured on the rear of the sled, in position to bear against the rod e5 is a spring E which acts normally to prevent disengagement of the notches from said tongue e7. Said rod lis provided with a handle at its upper end for manual engagement and by means of which the wheels are thrown into or out of operative position. i

The operation is as follows: The brackets owing to the extensibility of the rods D by means of a turn buckle may be secured upon the knees of any hand sled and adjusted so as to maintain the arms b for the front and rear Wheels in parallel relation both when the wheels are thrown upwardly as shown in dotted lines in Fig. l or when turned downwardly to support the sled and its load. The shoulders b2 of the brackets B and B/ or the set screws b3 therein act to rigidly brace said arms from being carried rearwardly by the resistance of the road or surface over which propelled. When the wheels are not in use the same are supported, as shown in dotted lines in Fig. l and the sled rests on its runners. The adjusting rod e5 firmly holds the wheels in either oi the adjusted positions inasmuch as the tongue e7 is held in engagement in a notch in said rod by means of the spring E Should it be desired to propel the sled upon the wheels the handle is pushed forwardly to release the adjusting rod c5 irom the tongue and the handle lifted to drop the wheels upon the ground. A slight upward pull on the handle, perhaps assisted by the toot which engages beneath the lever e4 lifts the sled forwardly swinging the same upon the arms l) to the position shown in Figs. l and 2 and the sled may then be propelled upon the wheels which owing to the shoulders b2 in said bracket are rigidly held from rearward movement.

The wheels and adjusting means therefor can be applied to any sled l'or ii the distance between the knees of the sled be greater or less than shown the rod D is shortened or extended by means ol its turnbuckle to maintain the arms b at all times in parallel relation to insure both wheels clearing when swung forwardly and also to insure uniform adjustment when supporting thc sled upon the wheels.

Obviously details oi construction may be varied without departing from the principles of my invention.

I claim as my invention:

l. A sled, wheels carried thereon, a rod connecting the wheels on the same side oi the sled and adapted to `adjust the distance between said wheels and hold the same in unvaryingl relation, a shaft journaled at the rear of said sleigh, an arm carried centrally thereon, a lever on each end ot.' said shaft, rods connecting each lever and the rear axles and means adapted to actuate said central arm to raise or lower said wheels.

2. A sled, front and rear wheels carried thereon and adapted to be adjusted downwardly to support the sled. extensible connecting rods connecting the front and rear wheels together on each side ol the sled and actingl to maintain the same an unvarying distance apart and means adjusting the wheels onto and ott' ol the ground.

3. A sled of the class described embracing the combina tion with the knees of a sled of brackets secured thereon. an arm pivotally connected in each bracket.. means on each bracket and adapted when said arlns are directed vertically downward to support the same against rearward movement, a wheel journaled at the outer end of each arm. and adapted to project below the runners. a connecting rod adjustable as to length and connectingl the axles of the lwheels on each side of the sled together and acting to hold upper end on said 'bracket and adapted to bear against the shoulder when directed downwardly, a wheel journaled at the lower end ol' each arm and adapted to project below the runner ot" the sleigh, an extensible connecting rod connecting the lower ends ol said arms together on each side of the sled and acting' to hold the wheels at unvarying distances apart, a shaft journalcd on the rear knee, l'orwardly projecting' levers thereon, one on each side oi' the sled, levers pivotally engaged at the axles ot' tht` rear wheels and enga ged on the inwardly directed ends ol' said levers, a rearwardly directed arm on said shat't, shaped to be engaged by the i'oot and an upwardly extending adjusting rod pivotally engaged on said arm at its extremity and notched l'or engagement with a suitable detent carried at. the rear of the sled and a handle on said adjusting rod.
